To all whom it may concern:

Be it known that l, HAROLD l). Vassnmrr, a citizen of the United States, residing at Fitchburg, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Bob bin Separator and Feeding Machines, of which the following is a specification.

This invention relates to the cbtton in- 1a dustry and particularly to the cleaning of bobbins used. therein and its object is to provide means for taking bobbins from a hopper and delivering them, one after an other, head foremost, into a stripping mais chine, which object is accomplished at presout by hand. The invention is illustrated by the accompanying drawings, in which Fig. 1 is a side elevation of the machine with the. sides of the hopper removed;

Fig. 2 is a rear elevation of the machine;

Fig. 3 is an elevation looking rearwardly from the line 3-3 Fig. 1;

Fig. 4t is a detail view ofa portion of the machine; and

Fig. 5 is a side view of Fig. 4:.

The frame of the machine is composed of angle iron members 1 fastened together by sheet iron plates 2; the hopper 6 is attached to cross pieces 11 bolted to the frame, the rear wall of the hopper being formed by the endless chain, or series, of equally spacedconveyors 7 affixed to the outer face of sprocket chain 8 which runs, rcarwardly inclined, over sprocket wheels 9, 9 fixed to shafts t journaled in bearings 5 bolted to the frame, said sprocket chain 8 being supported by strips 10 fastened to said cross pieces 11.

Shelf 16, preferably made of wood, is secured to side pieces 28 fastened to guide piece projected from chutes and has its lower end furnished with a knife edge 24 which is disposed adjacent sand roll 19 as (adapted to breakod loose threads) which is detachably mounted on the .frame and servesto prevent bunching of waste on said roll.

Chutes 25, supported by cross pieces 29 50 attached to the frame, are angularly disposed and lead downwardly to chutes 26 angularly disposed below them with their upper ends attached to brackets-30 secured to pieces 31 ailixed to the frame and with their lower ends secured to sides 32 of reservoirs 27, 27 from which, respectively, are projected brackets 33, 339.; there being hmged to brackets 33 at 35 swinging members 34- Which form the backs of reservoirs 27; and there being rigidly attached to bracket 33 member 34 which forms the back of reservoir 27.

A second endless sprocket chain 38, dis, posed rearwardly of and preferably at a ported by strips 48, which are supported in turn by cross pieces 4L7 affixed to the frame: and there being attached to the outer face of said sprocket chain 48 an endless chain, or series, of equally spaced conveyors 37.

Chutes 25, 26 are furnished with canvas coverings (not shown) for the purpose of confining the bobbins therein. 4

Pivoted bars 17, adapted to swing upwardly, are hinged to cross pieces 18 disposed on sides of hopper 6 and normally extend inwardly approximately to and at right angles to the outer ends of the opposite conveyors 7 these bars 17 prevent backward movement of the bobbins. Angular guide 44 (Figs. 4 and 5) and wedge-shaped guides 45 are secured to return chute 4:6 which is attached to cross pieces 47 affixed to the frame and leads to receptacle 49. Adjusting attachments 50 are also affixed to reservoir side 32.

The conveyors 3 7 are so formed and spaced as to carry, each, a single bobbin 'ly ing horizontally therein; a bobbin 413 (Fig.

4). that extends out over the edge of the conveyor is forced back into proper position'therdin by angular guide it," which operation is assisted by the rounded edge of the conveyor; or, if extending out too far for control by guide 44, the bobbin is forced out of the conveyor by wedgeshaped guide 45, into chute 46 which conducts the bobbins thrown into it and also surplus bobbins in reservoirs 27 to receptacle d9. Bobbins that are shorter than the length of the conveyor are adjusted by attachment 50.

Where two bobbins 51 (Fig. l), shorter than the length of the conveyor, occupy the same conveyor, lying therein with their heads in opposite directions, attachment
